ThrottleWatch
Is your Mac being throttled right now?
A lightweight menu-bar app that continuously monitors CPU thermal throttling and shows it live. The icon is a speedometer at full speed — it turns into a flame with the throttle percentage the moment the CPU is being limited.
- Privilege-free live metrics — speed limit, temperature, thermal level,
kernel_taskactivity - Real active CPU clock read in-process via IOReport — no root, no password, ~0.25% CPU
- Live scrolling charts plus a session summary with ring gauges and a per-hour heatmap
- Two chart renderers — SwiftUI Charts or a GPU-driven Core Animation path
